Dual Ramp Start
➀
This starting mode is useful on applications that have varying loads
(and therefore varying starting torque requirements). Dual Ramp Start
allows the user to select between two separate Soft Start profiles with
separately adjustable ramp times and initial torque settings.

➀ Dual Ramp Start is available only with the standard controller.
Full Voltage Start
This starting mode is used for applications requiring across-the-line
starting. The output voltage to the motor will reach full voltage within
1/4 second.
